HOWTO: Manage Access Control List (ACLs)

An ACL (access control list) is a list of permissions associated with a file or directory. These permissions allow you to restrict access to a certain file or directory by user or group. 

OSC supports NFSv4 ACL on our home directory and POSIX ACL on our project and scratch file systems. Please see the how to use NFSv4 ACL for home directory ACL management and how to use POSIX ACL for managing ACLs in project and scratch file systems.
